We live in a world that for centuries trained up its children in the classics, by this I mean the seven liberal arts: grammar, dialectic, rhetoric, arithmetic, geometry, harmony, and astronomy. These were followed by the queen of the arts: philosophy/theology.
Throughout those centuries, Christianity grew exponentially, Christians believed and trusted in the Triune God and His Word.
Today, our world refuses (or fails) to teach the seven liberal arts and our world (since the Enlightenment, I suppose) doubts or outright rejects the Triune God and His Word. For those who identify themselves as Christians, a multiplicity of them–according to statistics–do not believe in absolute truth or that the Bible is the Word of God.
Yet, somehow, there are Christians who oppose classical education (I hear Francis Schaeffer was one of them) on the grounds that teaching our children the pagan classics will teach them to doubt absolute truth and the inerrancy and sufficiency of the Word of God.
Allow me to repeat myself: for much of our history we taught our children classically (including the pagan poets) and Christianity grew exponentially and Christians presupposed God and His Word. Today, we fail to teach those things and we have failed to produce Christians who presuppose God and His Word.
Studying the classics (pagan and otherwise–there are Christian classics, you know) does not teach children to doubt or reject God or His Word, it teaches them to think. Rejecting the classics prevents our children from thinking and therefore seeing through the foolishness of this world, a foolishness that rejects God.
Embrace the classics, embrace thinking, embrace God.
